Leadership gurus are employed at business schools, where enthusiasm is an entrance requirement and optimism the stock-in-trade.(領導藝術大師受雇于商學院，在那里熱情是入門要求，而樂觀則是行規。)

I chose literature as my major subject, and I took no science until my junior year when, in order to meet the college entrance requirement, I took a chemistry course.(我的主修課是文學，沒有選修自然科學，高三時，為了考大學才不得不選學了化學。)

What is the minimum entrance requirement for this course?(這個學程的基本入學條件是什么？)
